Consider adding transaction hash to auto-generated Contracts object

[filippsen]

Summary

Add transactionHash field to auto-generated Contracts data object (accessible via this.Contract in app.js). In src/deployer.js:

(function(module, Contracts) {
var data={
...
address: "0x0...",
transactionHash: "0x0...",
network: "rinkeby",
...

Motivation

Can we get Tx hash from contract deployment below address* ?

• "below address" means the second line, inside the auto-generated Contracts data structure.

I prefer exporting ABI, contract address and transaction hash to a new JSON, skipping dependencies on built-in dapp and fallback to web3 contracts using ABI and contract address. The transaction hash is used to verify chain/network id, together with contract address.
